Letters Potent' N 96,406, d ltcd November 2, 1869; antedated October 30, 1869,

The Schedule referred to in these Letters Patent and making part of the same.

To all whom itnmy concern Be it. known that I, \V|LFRI-;D I. DUGDALE. of Goshen, in the county of Elkhart, and State of I ndiana., have invented a -new and improved Universal Shaft-Coupling; and I do hereby declare that thet'ollowing is a t'ull, clear, and exact description thereof; which will enable others skilled in the :njt to make and use the same, reference being had to the accompanying drawing forming .part'ot'rthis specification.

This invention relates to improvements in shaft:`

couplings, such as are used for coupling-shafts when required-to rnn out of' a right lille; 'and has for its object to pro-vide a. coupling ot' simple and cheap construction, whch maybe readily connected or disconnected, and having no projecting parts, such' as screw-4 bolts,vliable to catch into theclothing ot` attendants, and gather straws, &c., and istfdesigned, more especially, to beinsed with threshing-Inachines, but appliv cable to other uses.

The drawing represents sections of shafting, coupled together according to my improvement, the couplingblocks being shown in section.

I take blocks of metal, Afpreferably of cylindrical form, and make rectangulai- 'mortises in each end of greater breadth in one direction than the other, the

planes of the greatest breadth of each mortise' being necting the sections; also, that theconstruction is less expensive than any other.

These couplings answer-'fbi' shafts placed in a right.

line equa-llyas well as others.

Having th'us described my invention, l Vhat. I'claim as new, and desire to secure by Letters Patent, is-

The universal coupling-joints, consisting of the blocks A, lnortsed or recessed as described, and the enlarged ends B, lot' the shafts, fitted thereto, all substantially as specilied.
